Caledonian granite radiometric dating tests

Try It risk-free Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

It works because we know the fixed radioactive decay rates of uranium-238, which decays to lead-206, and for uranium-235, which decays to lead-207.

In fact, this form of dating has been used to date the age of rocks brought back to Earth from the moon.

So, we see there are a number of different methods for dating rocks and other non-living things, but what if our sample is organic in nature?

Radiocarbon dating, also known as carbon-14 dating or simply carbon dating, is a method used to determine the age of organic material by measuring the radioactivity of its carbon content.

So, radiocarbon dating can be used to find the age of things that were once alive, like the Iceman.

With rubidium-strontium dating, we see that rubidium-87 decays into strontium-87 with a half-life of 50 billion years.
